NAVCO pneumatic rappers set the industry standard for operational reliability, durability and overall dependability with a field proven track record in all climate conditions. In difficult rapping applications, NAVCO rappers are the rappers of choice. They provide maximum performance for:
high-resistivity fly ash in the power industry
salt cake in the paper industry
cement dust for both dry and wet process kiln precipitators and lime-kiln precipitators
smelter furnaces, BOFs, sinter plants, roasters and other primary metal applications
In challenging applications like these, NAVCO repetitive-impact pneumatic vibrators offer more uniform and better electrode cleaning than single-impact rappers. And their simple, rugged construction make them proven long haul performers.
Benefits
Teflon-coated piston and bore reduces friction and resists corrosion
Single moving part promotes reliable performance
Particle agglomeration is enhanced by adjusting time between rapping
No irregular dust layer is left on the plates
Standard 3 degree, 30 metric tapers for interference fit on steel-to-steel or steel-to-ceramic shafting
Operations
NAVCO pneumatic rappers are suitable for vertical or horizontal applications such as precipitator ash hoppers. In addition, their high reliability, high effectiveness and low maintenance make them ideal for bag house shaker applications.
